Stretch marks.. help!

Nicole • I am expecting my first baby which is a girl "Maliyah" November 2015. I am extremely excited about this Blessing💗👶🏽🎀
Will these stretch marks under my boons ever go away? Or does anyone know what I can use to help ? I've been using palmers coco butter stretch mark cream since I was 8 weeks pregnant and had absolutely no marks, and I recently noticed I have them underneath my boobs. Please help.
